VM operation is very convenient - easy backup, resource tuning... and sometimes restoring the older status - and what is the most important less eletricity.However... polarhome still runs on almost 10A (230V). There is no possibility to add some real HW servers because the fuse is 10A.

It is fun to know 30+ operating systems. They are all special on their way.My favourites are OpenVMS and AIX that win with a horse-length in front of modern Linuxes in administration and OS management - the pity is that they need very special hardware
